The increasing popularity of network computing and the shift away from the use of standalone computer applications have significantly changed the means by which computer software is developed and distributed. Software developers face a new set of challenges and require new tools to create applications and manage dataflow across a variety of computer systems. Web services combine a diverse set of software components to deliver custom functionality to customers. Significant architectural issues must be addressed during development of web services for interaction to take place and data to flow properly between the components of a web service and between various different web services.
